Study on Thermal Deformation of Machining Center’s Spindle Box Based on ANSYS

Article Preview

Abstract:

Thermal deformation of spindle box is an important factor affecting processing accuracy of the high precision CNC machining center. In order to research the distribution of spindle box’s thermal deformation, physics-environment method of sequential coupling analysis was used to analyze thermal-structure coupling with the finite element analysis software ANSYS. The results show that the rise of temperature of motor is the highest, and the rise of temperature of the back-end of spindle is the lowest. Thermal displacement on the front of spindle is the largest, and it is the main part that affects the precision of machining center.
